'Application inea mgm 9.41893. seria. Nt @aarzel (no modeler To all whom it may con/cern:

Be it known that we, CLARENCE and HARRY L. DOOLEY, citizens of the United States, residihgat Bloomington, in the coun- 5 ty of McLean andState of Illinois, have inventedcertain new and useful Improvements in a Combined Check-Row and Drill; and we do declare the following to be'afulhr'clear, and

ings, `'and to the letters and figures vot' refery 'encamarked thereon, which form apart of this specification. p y l The object of our invention is toobviate certain objectionable defects, in check row corn planters of the class employing e. rotat ing. or oscillating seed plate. In one construction, the rotation of the plate is'elfected whollyvthroughthe tappet wire, and this is disadvantageousbecause' the constant jerk ing of the wire loosens and pulls up the sel Y curing stakes, the wire is quickly worn and frequently breaks, and further it is not possible to check as straight as is desirable because of the work imposed on the wire. Another objection is inaccuracy in the number i of seed discharged at a time, due to the fact 39 that acell made large enough to hold several, say three, keranels of corn, will frequently get out more or less than this number;

In another construction of machine the seed plate is rotated continuously by suitable gearing, connecting it with the covering wheels, the seed being4 discharged from 'the box one -at a time by the seed plate until a given number has accumulated in the receptacle havo inga valve that is actuated by the tappet 4o wire. This ofcourse, relieves the latter of -wmfk as its S01@ duty isto Qneratetheyalre...

but, this'form of planter is seriously objec- Ytionable asobviously it cannot be depended on for accurate work, because owing to irregularities in the ground, the covering wheels will not always make the same number of one time more grains will be discharged to the tappet actuated valve, and at another In our invention we drive the rotating seed plate by means of the covering or carrying ""tmsmmwae H. Dooneyl exact description of theinvention, such as,

wheel or wheels,and thus free" the `wire of l this duty, and we use the wire,j(or rather the ,grains in every instance..

To the ends indicated, our invention' consists in the mechanism constructed substantially as hereinafter specified, and illustrated, l

in the annexed drawings, in whichframe, B, one of the covering and-carrying wheels, mounted on an axle b, and C, oneof the seed boxes or hopper, all of which maybe of any preferred construction. Within-the seed box C, is the rotating seed plate D having a numberofcellsoropeningsdeachlargeenough to pass but one grain of corn ata time tosuiti able delivering mechanism below. Said plate D is provided on the underside with peripheral, bevel gear teeth which mesh with a pinion e on a shaft E that extends across the machine to the other seed box, which, however,` is not shown, as the two are alike in construction. Just outside the box, the shaft 'E carriesa sprocket wheel f that is connected by a chain g with a sprocket wheel h mounted on a short shaft H about midway Between the seed box C and the .axle h. Loosely mounted on the outer end ot the shaft H is a. sprocket wheel rconnected by a chain j `with a wheel .I on said axle. It will thus be seen that-provision is made. to. revolve th e.. seed plate fromtheaxlc,

plate M and a bearing on said arm operates to normally swing the letter to place the so that its free 'end cenbe engegedhyn stop,

lug n one; sliding bei' N, which is connected to the redini erin o of e rock shaft that in *Jui-n iseonnected bymeens 'eefrediei femm@ end link orbsr o2 to the tsppetectneied lever P, of any usual construction. Movementef the lever P will through the connections just enumerated, slide the ber N so es to free the sr'm L from the stop (lug n and thus permit the wheel K and sprocket i to he clutched to the shaft H. Before the arm-L een coniplete its revolution, theftsppet will. release the level` P and through the action of as spring p, the slide will resume its-former position with'the stop lug n inthe' path ci end readyto engage 'the end of arm L, to swing it to lift its rollerrZ out of` engagement with the notched -rm ot' the .clutch disk K.' From theseed plate D the grains pass to ,s veived reoeptecle whose valves ere actuated 4from the rock shaft 0,whence they pass to the any suitable chute or guide.

The motions of our mechanism are so timed that the rotation -ol4 the 'seed plete is cornmenced immediately en the leveijheing'moved next tappet is reached, so that the corn is in the velved receptacle' ready. for delivery when always be discharged bysnid plete. The tiniing is such that the predetermined movement of the arrn L will always occur .in the interval of travel from one tappet to another. 0f

course, the timing of the gearingdetermines .the degree of movement of the seedplste et each operation end sccordingly the number of seed discharged to the valved receptacle.

We wish it understood that We do not limit` ourselves to the detsils of construction shown,

Y but regard ourselves as entitled to such veri- =ations therefrom as failwithin the scope of 4 om invention.- A
